# Pin the fork tip. 2860d75 = PR #14 merge "picture: bounds-check
# codec_store_buffer slice writes against source_size (#13)" — addresses
# marfrit/libva-v4l2-request-fourier#13. Guards the three append sites
# in codec_store_buffer's VASliceDataBufferType branch (H.264 Annex-B
# start code, VP8 uncompressed-header pad, slice payload) against the
# OUTPUT pool slot's fixed sizeimage; returns
# VA_STATUS_ERROR_ALLOCATION_FAILED with a request_log line instead of
# memcpy'ing past the mmap on a resolution upshift mid-stream (SIGSEGV
# in mpv --hwdec=vaapi-copy, heap-corruption hazard in Firefox RDD).
# The root-cause refactor (re-init OUTPUT pool / re-create surfaces on
# resolution change, or grow source_data on demand) is tracked as the
# follow-up backlog item; this PR is the memory-safety floor.
# Pin the fork tip. c454618 = PR #16 merge "picture, request_pool:
# transparent OUTPUT-pool resize on bitstream overrun (#15)" —
# follow-up root-cause fix to #13/#14. On a mid-stream bitstream-
# budget overrun (typical cause: SPS-driven resolution upshift in an
# adaptive-bitrate stream), codec_store_buffer now snapshots the in-
# flight surface's accumulated bytes, releases its OUTPUT pool slot,
# calls request_pool_resize (STREAMOFF → REQBUFS(0) → S_FMT with
# 2×sizeimage hint, capped at 1 GiB, page-aligned → CREATE_BUFS →
# mmap → media_request_alloc → STREAMON), re-acquires a slot, re-
# mirrors the surface's source_{data,size,request_fd}, restores the
# bytes, and continues. The frame survives instead of being dropped
# back to libavcodec for surface recreation. CAPTURE side untouched
# (per-queue V4L2 streaming independence).
